A report on highly viscoelastic and stiff gels in a nonionic-nonionic surfactant mixture system in an aqueous solution is presented. The effect of composition, surfactant headgroups and temperature on the micellar phase in nonionic systems is studied.

Structural evolution during the synthesis of mesoporous silica in fatty acid/aminoalkoxysilane/water systems

Article Abstract:

The phase behavior and structural evolution during the early stages of silica templating using surfactant liquid crystals in aminoalkoxysilane/lauric acid/water systems is reported. The results indicate three stages during liquid crystal templating, controlled respectively by self-assembly, hydrolysis, and condensation of alkoxysilane groups on the surface of aggregates.
